MANUFACTURE OF ARTIFIbIAL SAUSAGE SKINS Filed Dec. 2, 1941 milm l-fi xl Patented June 6, 1944 Julius Wolff, Amstenrade, Netherlands; vested in the Alien Property Custodian Application December 2, 1941, SeriaLNo. 421,397 In Germany May 3, "1937 13 Claims.

The presentlinvention relates to the manufacture "of artificial sausage skins made .of tubular fabrics impregnated with. suitable materials.

In known ,devicesfor themanufacture of artificial sausage skins of the kind mentioned above the tubular fabric is withdrawn from the impregnation mass and drawn upwardly through the annular gapof a stripping off device. The tubular fabric is withdrawnfroma mandrel which is arranged vertically in the tank containing the impregnationmaterial. A plurality-of impregnating devices with individual tubular fabrics are mounted in a row side by side so that a corresponding number of tubular fabrics may simultaneously be drawn upwardly.

-,I'hese known devices have the disadvantage that the tubular fabrics together withtheirsupporting mandrels are arranged .withinthe impregnation mass itself. Thus it is not possible or in any case it is very difficult to place large len ths of tubular fabric upon the supporting mandrels,

becallsethis would require correspondingly high tanks containing unnecessary large amounts of impregnation material. Moreover, it is .undesirable to leave alarge stock of tubular fabric, placed upon the supportingmandrels, in the impregnation mass longer than necessary which particularly would be very troublesome upon interruptions of service or at stops or intervals.

In accordance with thepresent invention these drawbacks are obviated by the fact that the tubular fabrics -to b impregnated are arranged upon long .mandrels below the tank containing the impregnation material, where they-are out .of

contact with the latter and, therefore, remain dry until the impregnation starts. To thisend, circular openings are provided in the bottom of this tank .in a number cQrrespQndingto the .mandrelsarranged below said tank. Mounted in these openings are cylindrical bushings provided at the ranged upon correspondingly longer supporting .mandrels which, moreover, may be provided below the impregnatingtankin a much larger number than hitherto. Furthermore, it is of advantage that within the impregnating tank only the stripping off devicesare present and not the supportingmandrels' with the tubular fabrics, whereby the entire operation is simplified and rendered easier to besupervised.

In the .accompanyingdrawing a device according to the invention is shown by wayof example.

In this drawing:

,Fig. 1 represents a general view of the device in front elevation showing a longitudinal section through the impregnating tank,

Fig. 2 is a side elevation showing a cross section through the impregnating tank,

Fig. 3 .is a broken away vertical section on a larger scale .of a .detail,

.Fig. .4 .is a plan view of theimpregnating tank and .Fig. '5 is afragmentary cross-section taken on the,line'5 5 .of Fig. 3.

The device consists of aframe 'I the upper end of which carries a horizontal trough 2 for the reception of the impregnation material. At the lower end of the frame a pan trough ,3 is provided to receive impregnation material which eventually may flow or drip off from the upper trough 2. In the bottom 4 of the upper troughZ a considerable number of circular holes 5 isprovided which serve the purpose of receiving cylindrical guide bushings 6. An enlarged supporting flange I is provided at the upper end of each of the bushings which by means of bolts 8 carry a ring 9 spaced a slight distance above the level of the impregnation material. On the central axis of each hole 5 a stationary mandrel l0 stands upon the bottom of the device and this mandrel is tapered from about the height of .the lower edge of the bushing 6 to the upper end. This tapered portion l 1 extends below the ring 9.

Upon theindividual mandrels l0 tube-like supporting sleeves [2 are pushed from above, the lower end of each of which is provided with a flange l3. Tightly sl pped over these sleeves is the tubular fabric I4 to be impregnated so that a length of about 100 meters of tubular fabric may be arranged upon each sleeve l2.

The tapered end II of the mandrel It carries members l5, l6 and I! having a convex surface by means of which the tubular fabric I 4 is slightly tensioned and stretched from within. Above the uppermost member I! an external wiper ring I8 is easilyslidabl on the bolts 8. The ring I8 is well rounded oil at its inner edge. The ring. has a smaller inner diameter than the finished tubular fabric so that the latter in contact with this ring is slightly contracted. At diametrically opposite points the ring I8 is provided with forked.

nected together by holding means 23 adapted to 1 be drawn upwardly by a suitable device to sus-,

pend the impregnated artificial'sausage skins and.

to dry same.

IAS the beams 22, or the holding means 23 are lifted, the length of tubular material is drawn;

upwardly htrough the bushing a. At this point the obturator l5, distends the tube and narrows the gap to an area allowing the passage of the tubular material only and preventin leakage of treating liquid in any substantial amount. The tubular material remains, distended until it passes the uppermost distending' element I! when it then is contracted by passage through the wiper ring l8" Thus the excess treating liquid is wiped off of i the tubular material. The latter above the ring will dry readily while suspended from the hook 2 I.
